Wireless Power Receiver IC
BD57011GWL
General Description
BD57011GWL is stand-alone integrated IC for wireless
power receiver. The device is composed fully
synchronous rectifier circuit in low-impedance FETs, Qi
compliant packet controller, Adjustable low-dropout, and
open-drain output terminal to communicate the power
transmitter by amplitude modulation.
BD57011GWL applies to 5W-power mobile application
based on WPC ver. 1.1.
